The hase portion o has screwthreaded into the neclt :l5ol' a shell 3G,

outwardly projecting ltiierel'roiii, dianietric` l the lower end otwhich is screw-threaded into ilo a socket 37 on the base portion of thevalve. The seating plug is inelosed by means of a cap 3S which isscrew-threaded onto the end of a neck 35.

ln the construction illustrated in'Fig'. 3, the nipple 20. instead. ofsupportingw a socket of the character hitherto described, depends fromand is formed integrally with a flooring 39 which. rests upon the flatupper face. ofthe hase portion of the valve, the socket 37 being;reliminated to permit the parts to rest in facial contact with oneanother. T he flooring has formed around its edge a rim or flange 40,screw-threaded on its interior, which rim or flange has enteredthereinto a dome-shaped casing 4l.; li'ithin the casing is located aiioat 42 of the usual type., which lioat is adapted to rest lupon alug43 on the iloor of the valve casing, which raises the floatsutilciently to permit the easy ingress of water, The iloat carries nearits top a small sind i4 which engages with one end of a lever i5 whichis mounted ony a pivot -le and is )ro vided at its opposite end with aclosing bl oclr 47. The closing block is ada )ted to be seat ed againsta nipple 48 entered into the upper end of a dischargeiipo 49, whichlatter is en,

tered through the oorine` of they valve casing and is in alinement withone of thc discharge passages 26. The flooring*7 on its under side, isprovided with an annular recess 50 into which the pipe 4) enters, withwhich annular recess both of the discharge passages 2Q are incommunication.

ln order to facilitate the adjustment ol' the valve of either style, adial `ilatel is emiloyed, which is secured to t-lie1ncck' ll and 1sinscribed with suitable words indicating: the positions to which thevalve may be turned, as, for instance, Open, "losedf and Drain, or wordsof similar import.

In use, when it is desired to have the air valve operate automaticallyoriu its normal mannelgtho valve plugl is turned into the positionindicated in Figs. l, 2, and 2S, which permits the air esca une from thehea-ting system to pass througii the valve plusT and up to the operativeportions ofthe valve. ll'hen it is desired to drain the system orprovide fora more rapid discharge of air, the valve is turned intoposition tobring'the passage 17 into register-With the discharge port 2lwhich provides a direct passagefor the escape ol` air and facilitatesits discharge. l

.'5 ll desired, the valve can he shut ol` entirely by turning theiassage i7 half way around, which completely shuts ol' the discharge ofair or water through the valve, 'This latter adjustment can be made Whenit desired, tor any reason, to remove the valve casing or disconnect thovalve at its lower end.

ln the valve ol Figs. l and 2, the air7 passiug through the air plug.will pass upwardly through the tubular vulcanite post7 thence 63'downwardly within the casing' 4and through -said passageways,

'either or both of said the discharge passage 26. This action willcontinue until the system has beenrelieved'` Vtroni air and the steambegins to enter the; f valve. As in all air valves ot' this character,the steam serves to expand the vulcanite' post and prevent furtherescape of air and stearn from the valve. A

The valve oi Fig. 3 differs only from the, hitherto described in that afloat of the' or' dinary character is provided in place of the e5expansible vulcanite post, which iioat will be raised as soonras thesystem has been relieved from air and water begins to rise in thevalve;v

The riseol the iloat serves to close the pipe 1 49, thereby preventingthe iurtheedischarge of air or ivater through the valve. So far as theauxiliary mechanism, Which more particularly forms the subject matter ofL the present invention, is concerned, suoli.; mechanism is exactly thesame in'both cases,v the only features of ditierence being such asgenerally pertain to valves of the two differ-- ent st vlesabovedescribed. v -f The invention is one which enables the L" in aheating; system tolse more quicldy and more easily discharged, by propermanipula# y tion oi the valver than by the normal opera-g tion of thevalve. In many cases it is highly desirable that theradiators be. morerapidly? heated than is possible 'wherethe air is per- '95 mitted .toescape by a circuitous route throughthe valve ordinarily provided. Theinvention furthermore permits the air to be vented` in cases in whichthe valve meoiianismfbesf comes disordered, so' that no difficulty Willbeev experienced in bringing the radiators to the required temperature,even though -the valve he out ol commission. The valve furtherl providesmeans for quickly draining the sys` tem of surplus water or Water ofcondensation, and provides a closure, which.. )ermits the valve casingto be removed and t e'inte rior mechanism to be repaired or renewedwithout the. escape of any Water or steamfrom the radiator. v jug,
